Oliver Hirschbiegel‘s best-known film to date is probably Downfall, a.k.a. the movie used in the “Hitler Reacts To” meme. But for his newest biopic, he’s tackling a much less controversial, far more beloved leader.

Diana follows the People’s Princess (played by Naomi Watts) and her passionate romance with Dr. Hasnat Kahn (Naveen Andrews of Lost fame) in the last years of her life. The first teaser released earlier this summer was little more than a collection of images set to music, but the first full-length trailer from Australia offers a better look, with actual dialogue and everything. Check it out after the jump.
